This is an application designed for engineers but can be used by anyone. Once you open the app you’ll see a simple calculator with a swipe keyboard but there’s much more behind.

This is a powerful application which has the following features:

- Equation Solver: You can solve almost any equation. It supports:

-> Non-linear equations: Any type of equation, such as: 5*x+sin(x^3+2)=8 (up to 10 equations and variables, you can see 2 equations solved in the screenshots)

-> Linear equations: Like 2*x+3*y=8, -3*x+6*y=3 (up to 10)

-> Polynomials: Up to grade 20 (complex and non-complex solutions)

- Interpolation

-> Simple: Perfect for thermodynamic tables with only one variable (for example Temperature)

-> Double: 2 variables interpolation. See screenshots for a preview

-> Points to line: If you have a set of points (x,y) this tool will find the closest line and will give you the R^2 (Just like Excel).

- Function editor: Create as many functions as you want and save them under different categories. Using custom functions is extremely easy and very helpful. You can describe the functions and variables. Furthermore, you can take a photo that may help you understand and use the function correctly. Functions can be used in the calculator as well as in the equation solver.
